kernel panic, no init found

[Jianming YOU <youj@fnal.gov>]

Hi, Experts,

I just upgraded my box from 2.0.34 to 2.2.1 and I got
"kernel panic, no init found..." when I tried to boot with the new
kernel. The problem have been reported by several people. However, I
still don't know how to recover the system after reading those replies,
:(.

I'd appreciate if anyone can outline a procedure to recover from this
situation. For the moment, I can only boot with a 2.0.34 floppy and see
the hard disk.

Any guidance is very much appreciated.
